The driver that supports the ADV7282-M also supports the ADV7280-M, ADV7281-M, and ADV7281-MA. The 7280-M exposes 8 analogue inputs. The 7281-M doesn't have the I2P deinterlacing block. The 7281-MA has 8 inputs but no I2P. Otherwise they are the same as ADV7282-M. Adds a new overlay "adv728x" that includes the existing adv7282 overlay but adds several parameters to modify the behaviour. Adds a new addr parameter to allow the I2C address to be changed. (the chip has an address select pin to change between 0x20 and 0x21). Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
